WATCH: 14 accents in 84 seconds

Can't tell your Liverpool accent from the Yorkshire? Let a Hollywood speech coach tell you how.
Andrew Jack has coached actors on Batman Begins, Lord of the Rings, Sherlock Holmes, among others.
Here, the dialect coach does a tour of the British Isles with 14 accents in 84 seconds. It's rather mind-blowing. Jack did the report for BBC's Channel Four.
